Perseus, the rescuer of Andromeda, had a quest to bring back the head of Medusa. Not knowing her whereabouts, he went to the three sisters of Polydectes, who were blind and shared a glass eye. They refused to help him until he stole the eye and would not return it until they told him where to find Medusa. Using a shield given to him by Minerva, he avoided looking directly at Medusa and beheaded her. Pegasus sprang out of the Medusa's blood and he rode him back to Artos, where he found Andromeda chained to the rocks as a sacrifice to Cetus. Using the Gorgon's head, Cetus turned to stone. Perseus and Andromeda fell in love, and both were placed among the stars.
